Mining of methane from deposits subaquatic gas hydrates using OTEС [PDF]
E3S Web of Conferences, 2021 The article proposes to using Ocean Thermal Energy Conversion (OTEC) to increase the energy efficiency mining of methane from deposits subaquatic gas hydrates on the gas hydrate cycle (GHET), that will allow not to spend 10-15% of the extracted methane ...

Intensifying the process of methane gas hydrates crystallization in the presence of surface-activated substances [PDF]
E3S Web of Conferences, 2021 The crystallization process of gas hydrates during their formation in the presence of surface-active substances (SAS) is studied. The research is conducted in two directions – theoretical and experimental. Experimental data on the crystallization rate of

Modeling the climate response to a massive methane release from gas hydrates [PDF]
, 2004 [1] The climate response to a massive release of methane from gas hydrates is simulated in two 2500-year-long numerical experiments performed with a three-dimensional, global coupled atmosphere-sea ice-ocean model of intermediate complexity.
